Ryan, who split from Reese in 2008 and quickly began dating Australian actress Abbie Cornish, said in May that the former couple are on good terms.

'Things are great,' he said.

'It is so important as divorced parents to keep that connection. It makes the kids feel better that the parents are interacting.

'We go to all the school events together, and we're there for each other.'

In
a separate interview, he added: 'If the kids care about mom and dad,
and if that's consistent and they feel protected that way, they don't
they don't really care so much about who the parent is dating. They just
don't.'

Ryan is now said to be romancing actress Amanda Seyfried, whom he met at a Halloween party in October.
